This utility uses two input DEMs (i.e. raster files of digital elevation models) located at the exact same spatial position but at different elevation and calculates a specified number of raster DEMs located at equidistant distance between them (i.e. for n=1, one new raster located precisely in the middle will be created).
createIntermediateRasters --file1 <file1.asc> --file2 <file2.asc> -o <output.asc> [-n <int>] Where: --file1 <file1.asc> (required) First DEM-raster file --file2 <file2.asc> (required) Second DEM-raster file -o <output.asc>, --output-file <output.asc> (required) Raster output file (*.asc) -n <int>, --number <int> number of rasters to be calculated
n determines how many layers are created between the two input layers. If the parameter is not specified the default value is set as
Two input rasters as well as their 3D surface representation. Darker pixels represent values at a lower elevation while brighter pixels represent higher elevaton. In the 3D visualisation, the left-most raster is represented by the green surface and the right-most raster by the yellow surface.
createIntermediateRasters --file1 raster1.asc --file2 raster2.asc -o output.asc -n 1
A new raster is created in the exact center between the two input rasters. In the 3D representation, the new layer is shown in red.
createIntermediateRasters --file1 raster1.asc --file2 raster2.asc -o output.asc -n 2
n>1 multiple rasters are created at equidistant distances between the two input rasters. For
n=2, two new rasters are generated, represented here in red and blue.
This utility allows to generate additional input data when creating a bulk mesh from geometry and raster layers. The existing layer structure given via raster files can be refined to avoid deformed elements if the resolution in x-/y-direction is significantly more detailed than in z-direction.
